GE Zenith* STS-1 Series, Single Phase, 25-85Amp [BR]
GE Critical Power is a supplier of static transfer switches to a wide range of industries. The GE Zenith STS-1 Series static transfer switch supplies critical loads with a choice between two available sources of electrical power. By continually monitoring power quality, the STS-1 switch automatically transfers to an alternate source without interruption of power to even your most sensitive critical loads. With a sense and transfer time of less than 6ms, the STS-1 represents the highest performance power switching solution available.
Wide Product Offer Range
- 25 thru 85Amp
- 120, 208, 240VAC
- Source Default Select option enables manual selection to determine which source the switch will normally run on if both sources are present.
